Perceptual Qualities of Space
Language of Materials vs. Feel of Spaces
This map shows the city of Chicago broken down into a color diagram based on the materials of each of the buildings. It maps the use of brick on buildings (red) and the use of wood on buildings (yellow). These two colors show the break down of the buildings according to commerical use or residential use. This map is useful for showing the divisions of Chicago according not only to the material of the building but also the program and use of the building as well.

Flat, dark-colored roofs like those on many retail centers, apartments, warehouses and offices can exceed 160° F. in the summer, enough to affect the temperature of whole neighborhoods. Greater use of more reflective roofing with high albedo (a measure of the reflectivity of solar radiation) helps cool urban air temperatures. Greater use of green or garden roofs also reduces urban temperatures and help reduce runoff that contributes to flooding. Cool
A dark surface on parking lots can reach 160° F. or hotter. Parked cars on hot pavement emit gasoline fumes contributing to air pollution. Rainfall on this surface is heated before it flows into waterways where it harms temperature-sensitive species and carries heated pollutants into our streams. Light-colored pavements offer a cooler alternative, reducing surface heat and lowering the temperature of stormwater runoff. Porous paving offers a good solution for low traffic areas such as parking lots and light duty roads, cooling the city and reducing urban runoff. The Cool Houston Plan provides information on paving technologies and a course of action on encouraging their use.

This article talks about three very important aspects of Urban street life and the materials used to help with the comfort levels of the people using the streets. This article was written about houston but more of this will apply to Austin as well.
